This collection is the best box set i have ever found and it has all of Clapton's best works.

I am typically not a big fan of box sets or greatest hits collections. This, however, is a must have for anyone who is interested Clapton or rock n' roll history.
You don't just get Clapton on this. You get John Mayall, Cream, Bob Dylan etc. All the bands he's been in.
It is revelation to see just how pervasive Clapton was as a guitar player. He's done it all and played in every style imaginable while still maintaining his signature sound. He shines on every track.
This collection is well thought out and arranged. It does not simply exploit the greatest hits. There are many gems on here that you won't be able find anywhere else. Moreover, you get a real sense of his development as a musician and singer.

Eric Clapton has been through several different phases musically. He started off at sixteen or seventeen, singing Chuck Berry's "Roll Over, Beethoven" at a nightclub in London, and according to some accounts he didn't even have a guitar of his own at the time (the tougher, slightly older "in-crowd", which included Mick Jagger, Brian Jones and Keith Richards, called him "Plimsolls" because of his habit of shyly looking down at his shoes while he sang).

Then came the British blooze of John Mayall and the Yardbirds, the fiery power-trio Cream, the short-lived Blind Faith, the phenomenal Derek & The Dominoes, and the many solo albums which quickly came to include as much pop, country, reggae and music hall as they did blues.
And it's all here. Every truely essential song Eric Clapton recorded during the 60s, 70s and 80s is here, along with a few live tracks and rarities. Not many, and not enough to really interest the serious Clapton collector, but this box set wasn't meant to add a new dimension to EC's catalogue, it was meant to present a complete overview of his long and varied career, and it does that perfectly.

"Crossroads" came out two years after Bob Dylan's "Biograph", and helped establish the boxed set as a viable proposition for record companies, and it includes seventy-three of Clapton's and his various bands' best songs.
It leans quite heavily towards his 60s and early 70s output (only about a dozen songs were cut after '74), and draws nine Yardbirds-tracks, six Bluesbreakers-tunes, twelve Cream-tunes, and three Blind Faith-tunes from EC's checkered past, as well as a Delaney & Bonnie-song ("Comin' Home"), and no fewer than ten Derek & The Dominoes-chestnuts (they only ever put out one studio album).
And then there's my favorite track of the whole lot, a supremely catchy, acoustic, slide guitar-driven rendition of T-Bone Walker's "Mean Old World" performed by Clapton and Duane Allman (and mistakenly credited to Little Walter Jacobs).

But there's a lot of other great songs here....in fact, there aren't very many songs here which aren't great.
I don't agree completely with the compliers' choices as far as Clapton's 80s output goes, but most of this set is simply magnificent.
This may not include everything you could ever want to own by Eric Clapton (he has made music since, and he cut some great live records in the 70s and early 80s), but it is a very thorough and well-chosen collection, and if you're a casual fan of bands like Cream and the Yardbirds, this set is pretty much everything by those two combos you'll ever need to own.
"Crossroads" came out fifteen years ago, but is still one of the finest career summaries on the market.
Highly recommended.
